N/A; Due to limited knowledge and inability for testing each and every species, the reactivity of the antibody may extend to other species which are not listed hereby.

Human IL4; Since it is not possible to test each and every species our knowledge on the corss reactivity of the antibodies is limited. This particular antibody might cross react with speacies outside of the listed ones.

For short term storage keep the antibody at +4°C. Variations in the range 1°C to 9°C are tolerable. For extended periods of time aliquote keep the antibody at -20°C. Cycles of freeze/defrost may denaturate the antibodies, thus reducing their activity..

Interleukin 4 (IL4) is a cytokine that induces differentiation of naive helper T cells (Th0 cells) to Th2 cells. It is used for dendritic and T cell therapy. Upon activation by IL-4, Th2 cells subsequently produce additional IL-4 in a positive feedback loop. The cell that initially produces IL-4, thus inducing Th0 differentiation, has not been identified, but recent studies suggest that basophils may be the effector cell. It is closely related and has functions similar to Interleukin 13. Recombinant, GMP rec. E. coli interleukin-4 for cell culture supplied by GENTAUR. Free samples on request.

If you buy Antibodies supplied by MBS Monoclonals they should be stored frozen at - 24°C for long term storage and for short term at + 5°C.This MBS Monoclonals Fluorescein isothiocyanate (FITC) antibody is currently after some BD antibodies the most commonly used fluorescent dye for FACS. When excited at 488 nanometers, FITC has a green emission that's usually collected at 530 nanometers, the FL1 detector of a FACSCalibur or FACScan. FITC has a high quantum yield (efficiency of energy transfer from absorption to emission fluorescence) and approximately half of the absorbed photons are emitted as fluorescent light. For fluorescent microscopy applications, the 1 FITC is seldom used as it photo bleaches rather quickly though in flow cytometry applications, its photo bleaching effects are not observed due to a very brief interaction at the laser intercept. MBS Monoclonals FITC is highly sensitive to pH extremes.
